onsemi has unveiled its latest silicon carbide technology platform, the EliteSiC M3e MOSFETs, to significantly improve energy efficiency for power-intensive applications. The EliteSiC M3e MOSFETs are designed to reduce turn-off losses by up to 50% and conduction losses by 30%, thanks to onsemi’s unique design and manufacturing capabilities. These advancements are built on a proven planar architecture, making the platform ideal for a wide range of automotive and industrial applications, including electric vehicle powertrains, DC fast chargers, solar inverters, and energy storage solutions. The technology promises to support the transition to more efficient, higher-power data centres crucial for powering sustainable artificial intelligence engines.
Simon Keeton, Group President of the Power Solutions Group at onsemi, stated “Today’s infrastructure cannot keep up with the world’s demands for more intelligence and electrified mobility without significant innovations in power. This is critical to the ability to achieve global electrification and stop climate change”. He emphasised that onsemi’s ongoing innovation aims to increase power density in silicon carbide technology to meet the growing energy demands.
The EliteSiC M3e MOSFETs, featuring the industry’s lowest specific on-resistance (RSP) with short circuit capability, are particularly suited for the traction inverter market, which dominates silicon carbide volume. Packaged in onsemi’s state-of-the-art discrete and power modules, the 1200V M3e die offers approximately 20% more output power in the same traction inverter housing. Alternatively, it enables designs with 20% less silicon carbide content, reducing costs while allowing for smaller, lighter, and more reliable systems.
Dr Mrinal Das, Senior Director of Technical Marketing at onsemi’s Power Solutions Group, added “There is a huge technical interdependency between the materials, device, and package in silicon carbide. Having full ownership over these key aspects allows us to have control over the design and manufacturing process and bring new generations to market much faster.”
onsemi’s broader portfolio of intelligent power technologies, including gate drivers, DC-DC converters, and e-Fuses, complements the EliteSiC M3e platform, enabling advanced features via integration and lowering overall system costs.
